Unlock complete reportThe five-unit residential building at 3519 W North Ave in the Humboldt Park neighborhood was constructed in 1906 and is currently owned by Alejandro Flores. The property has experienced some recent activity worth noting, particularly throughout 2025. Most significantly, on September 17, 2025, three periodic routine inspections were conducted that resulted in open violations, though the specific nature of these violations is not detailed in the record. Earlier in 2025, there were several service requests made through the 311 system, including a no water complaint on February 22 (which was subsequently closed), a porch inspection request on September 4 (also closed), and a graffiti removal request on December 17 (which was closed). The building's total recorded violations and service requests over the past seven years remain relatively low, with only three violations and three 311 service requests on record, though the recent clustering of service requests and unresolved violations suggests increased activity in and around the property.

How 3519 W North Ave's risk score is calculated
We trained a model on 7 years of Chicago code enforcement data — building violations, 311 complaint history, environmental enforcement, and owner track records. It estimates the probability that the City of Chicago will find a code violation at this address in the next 12 months. Lower % = safer.
What the score means for you
Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Higher risk — riskier than most nearby
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 6229 buildings in this neighborhood, 5295 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
